Abstract

The existence of a body centered tetragonal phase of Cu has been investigated in this manuscript when the single crystal FCC Cu is subjected to both high pressure and high temperature. The results have been demonstrated through DFT calculations (which are typically done at 0 K) followed by Helmholtz free energy calculations (for high temperature). The new metastable phase of Cu demonstrates higher thermal conductivity compared to that of the FCC phase and thereby may be beneficial for high temperature engineering applications.
